To all whom it may concern.'

Be it knownthat I, LELAND M. VAN SLYKE, a citizen of the United States,residin at Chewelah, in the county of Stevens and tate of Washington,`have invented certain new and useful Improvements in `Wood Sawing andSplitting n Machines, of which the following isa specification.

The resent invention relates to improvements 1n wood sawing andsplitting inachines, and is designed particularlyfor use as a portableapparatus, adapted to be transported over the round and used `in thewoodland for sawing and splitting the entire fallen tree into stovelengths for rewood.

The primary object of the invention is the provision of an apparatus ofthis character that is compact and simple both in construction andoperation, may be manipulated with facility to save the expense oflabor,

andwhich, withal is well adapted for per-` forming the functions of animplement or apparatus of this type. e i

y the utilization of the implement a fallen tree, after having beenstripped of its branches and foliage, is, with facility and despatch,drawn or hauled by devices form-` ing part of the "implement, toward theimlement, and successive lengths sawed thereom, and while the succeedingsaw cuts are being made, the blocks ofsawed wood `may be split into`proper size by another part of the mechanism of the implement, and theine vention consists in certain novel combinations and arrangements ofparts of .thejimplement or apparatus, whereby thesey func-e,

tions of themachine are carried out. n

In the accompanying drawingsY one complete example of t e physicalembodiment of the invention is illustrated, according to` the best modesojfar devised .for the practical `application of the principles of theinvention.

Figure 1 is a top plan view of the implement embodying the novelfeatures of the invention, showing the implement attached to a treestump and in position to haul a fallen tree to position for sawing.

Fi 2 is aside elevation of the machine,

showing the sawing voperation and also the wood splitting devices.

Fig. 3 is a front view of the wood splitting device, detached, andpartly broken away for convenience of illustration; n

Fig.` is a sectional viewof vthe platform or skid, showing the manner ofadjusting the boom of the derrick of the splitting `device.`

Fig. is an enlarged `detail showing a star wheel atone end of one of thebrace rods usedin connection with the stump of the tree to which theimplement is anchored.

As before stated the implementis adapted for use in the woodland andistransported or drawn over the ground, tol follow up the felling of treesand to cut and split the timber into lire-wood size.

The preferred embodiment of the invention is 'illustrated in thedrawings, and for convenience of description the fallen tree is edesignated T, the stump from which the trunkhas beensawed is indicatedas S and thesawed block of wood, ready to be split n i into proper sizeis marked B.

Theimplement is drawn or transported `over "the surface of the groundand therey fore the platform 1 has a pair of runners or` `skids 2,- 2,beneath it so that whenthe proper power is applied,A as horsepower, theimple-` ment maybe moved from place to place, and is operated throughthe instrumentality of the metor or gas engine Shaving the usual ioperating mechanism 4: to actuate the cross cut saw' `5` that isdesigned to" cut the trunk "I, in a vertical plane, and the splittingorchopping device indicated as a whole by the numeral 6 isalso` designedto be actuated in a vertical plane to chop or split into proper sizesthe blockB.`

` Afterfthe implement has been transported to properposition it isanchored 'to the tree stump S" by meansbf the chain 7 which is attachedto the platform at 7 and wound, once, around the stump and passed overthe e pulley Tathat is temporarily supported on the stump, and bymeansof the take up device` indicatedat 8 the slack` in` the chain istalrenup and thechain drawn tw'aut. The end ofthe platform is curved, asat C, to accommodate the stump and by meansof the brace bar 9 and bracerods 10 the implement `is held stable withrelation te the stump.` e.These braces arepivoted tothe platform 11, andare disposed so that theyradiate from "the approximate center of the stump, when in position, andincline up wardly from their their X free ends, whic lvoted ends, sothat p carry each` a star wheel 12, will contact with the surface of thestump through. the instrumentality yof these wheels., and when thebraces are forced falling away from the block as the operationprogresses. This flexible ,resilient chain is provided with springs 30connecting its scc- -ldownwardly the free ends= of the braces,l tions,and four diametrically arranged supwhich are bifurcated for the starwheels or porting chains 81 retain the resilient binding ratchet wheels,.are Alowered and cause the teeth of these star wheels or ratchetwheelsto engage or bite in to the surface of the stump. The v,free ends ofthebracesare forced downwardly by applying avwrenchY or other toolftothesquared end 13 of the wheelaXle, and, then after thebraces lhave. beenforced intoproperposition, the locking u pin 14 is passedthroughopenings in the end '10 .forthe purpose, to lock 1the ratchetwheelfagainst, movement. In this position the implement iis/.anchored tothe tree stump., with stabilityfsuiicientto support and allow.

movement of plement.

yBy means of the the working', parts of the` iinhauling rope .15 on the.drum 17 the tree trunk T is-now hauled to position for sawingintoproper. length, land if necessary the idle ,roller 16 maybeutilizedeither `forl the rope or to prevent the trunk:

rubbing against the implement. Through the medium-of the druml'? Vandthe driving gears 15 of thet engine-,therope is wound upon the drum. andthe trunk .is pulledpntor and supported by therollers `18. These rollersarelpreferablyarranged in pairs, with their. axes parallel with the'lineof move.- ment of the saw, andarecurved to. conformr to thecircularlines'ofthe trunk, and they provide a cradleqfor the trunlnwhileit is being sawed into lengths, stakes20 being attached to the frame y19of the rollers for holding y the. cradle in rigid position, itbetrunlcit is split up intoproper size through the use ofthesplittingdevice 6 which is supV ported from theplatformiof theimplementchain in place by their connection, in pairs,

to the guide ybars 2.4, and to the fixed brackets 32 projecting upwardlyfrom the base .block 26 to which they are attached. Thus,

as the circular or cylindrical wood block yis split into successivesegments,the bunch of segments are held in approximate.cylindrifl calshapebyfthe resilient chain, so thatlthe splitting device 6, which iscapable of rotation horizontally,ymay be made to split the `blockinto'comparatively small pieces.

The splitting member comprises a head .33 iii the shape of a roundflatdislr, and the upper weight-disk'34, having theswivel bolt 35, andthe splitting member has diametri- .cally arranged guidearms 36 adapted"to slide over the two bars 24 of. the derrick andy reciprocatingmovements. The cutter of the device has four blades 37, arrangedwasshown guide the splitting member yin its vertically to cut the blockintoA four quarters at eachy stroke, and these cutters are fashionedwith beveled or wedge portions 38, which, as the blades descend Aintothe block, force the quar- .l

., resilient binding chain ,29 co-actswith these" ters outward radiallyto `provideproper clearance for.` the cutting blades, and :the

after whiclithe-chainrreturnsfthe bunch of .segments tocompact, alined,position ready for thenext stroke. y The splitting member is operatedthrough theagency of the Vcon.y ing tunderstoodrof course ,that thestakes.A
